Heat during summer

Have you tried one of those fans from a movie studio, the ones they use to simulate a hurricane? I bet that will cool it down.

 

here is a link to a fan i purchased from marinedepot for $23.99. it dropped my tank 3 degrees. I've recently added MH lighting and so far it's keeping things under 81 degrees. we'll see how the summer goes, but so far so good.

What Otty said. I went with the house ac last summer and it only kept the tank at around 83-84. I finally went with a chiller and would never look back. Keeps the tank at a constant 80 all day, now I won't have to run the ac all day, which if you think about it would cost more then the chiller in the long run

 

I ordered this fan as well. I just wish it came in black...8)

 

you can get the same size fan at wally world for about 9 bucks. Just a thought.

 

This may not be the most environmentally friendly method, but if you pay a flat fee for your potable water, you can try the following cheap and dirty fix if your cold tap water is reasonably cool: hook a hose from your tap and then connect it to a vinyl hose (or similar) and coil it around in your sump to give maximum contact time/surface area between the coiled hose and the warm aquarium water in the sump, then place place the end of the hose in a drain and send the tap water down the drain. The cold water running through the vinyl hose in the sump should provide a few critical degrees of cooling if the tap water running through the hose is considerably colder then the aquarium water. Like I said not the most efficient way of cooling your aquarium water, but its a good back to have during a really hot day and your tank temperature is rising to critical levels. I bought a chiller for my tank about 6years ago....
